Hi, everyone,

i install sap netweaver 2004s sr2 in the Windows server 2003 standard x64 with SQL server 2005 sp1.

jdk: j2sdk1.4.2_12-x64

The installation components are :

AS abap

AS java

EP

EPC

BI java

DI

In the step "start java engine", it can't start and installation process abort.

In the SAP Management Console, it can't see the "J2EE Process Table".

In the sapinst_dev.log, it shows below INFO:
